DOUBLE SEAL SIDING Filed NOV. 28, 1942 Patented July UNITED STATES PATENT OFFICE Herbert rz e grllfim f uf iasdmor to Application November as. rsiz. Serial 'No. wars 3 Clalms.- (01. 20-5) to provide a siding which is wind and weather proof and will prevent insects and the like from entering.

It isan object 01 the invention to providea clap board or lap siding which has three lines oi! wind and weather seal. It is an object 01 the invention to provide a clap board or lap siding which has no exposed nail holes nor any need for putty.

, It is an object of the invention to provide siding or clap board which is firmly held at both top and bottom and give the lap desired.

It is an object of the invention to provide a siding which greatly reduces the cost of upkeep.

It is an object of the invention to provide siding which when used in short pieces as between doors and windows, danger oi! split ends and the like requiring special treatment is eliminated.

It is the object oi! the invention to provide a double seal strip which is reversible so as to place siding up under windows and doors and over windows and doors.

It is the object of the invention to provide a siding that still retains its colonial appearance.

It is the object of the invention to provide a special double cutter which cuts both the double end groove and shoulders with one operation. I

'weather sealed strip.

Fig. 4 is a perspective detail of a double cutter which cuts both the double end groove and shoulders with one operation.

In the drawing like numbers refer to like parts throughout.

Means or studding ill supports sheathing H which is nailed or otherwise secured in place. At spaced intervals along the siding i 9 are nailed wind seal l2. Wind seal strips I! are provided with a substantially rectangular base it which sets firmly against the siding. A rounded outer portion ll projects from the base "and is provided with inward channel ii. The outwardly extending portion I4 is provided with rounded be orany desirediorm, msmmasapme as l shown in Figure l. A groove or channel generally curvedin form is located in the rear face or the covering material it. The channel is adjacent the edge or the covering material and the channel defines two tongues 35 projecting toward each other outlining grooved walls 23 and 24 having a radius 01! curvature such that the grooved portion I! of the wind seal strip fits therein.

In applying the seal strip I! such strips are secured at desired intervals to the sheathing.

The siding I9 is then adjusted so that that por-.

tion oi! 'll of strip i2 fits within the channel in the siding and the grooved portion l8 fitting snugly against the grooved surface 23 or 24 with one of the projecting members 35 fitting snugly 1 they interfit is evident. In actual practice .there into channel it. The covering material'such as clap board I9 is then firmly, secured in place by securing means such as means 25. It will be seen that when two clap boards are put in place, the securing means is completely covered as shown in Figure l and no nail holes are exposed for counter-punchin puttying and repainting.-

It' will be seen that the clap board is firmly held in place both at top and bottom and that the three points oi'windand weather o p e are obtained. One line" of stoppage is at the butt end of the clap board along'line'lt-a second line is at the meeting or curved surface 23 and'portion ll. A thirdlinefis at; the meet are shown spaced in Figure l-this showin is merely for cleamess so that the manner in which is line or surface contact between. .the parts at 28, 21 and 35 as described above. This eflectively Iormsa three point seal. It will be noted also that between 26 and 21 there is a dead air space 29 which is or real value in construction of this type since here the energy of any air which may have gotten past seal 26 is dissipated and has a greatly decreased chance oi. getting past seal 21. The upper portion of Fig. 1 shows a second method oi. applying the lap-siding and also illustrates something of the flexibility of positioning provided.

In general it is desirable to have the tapered siding about some seven inches in width with a inch butt edge at the bottomwhere it is tapered and running to a /m inch at the top edge. Channel 20 is preferably about 1%.inches in width and about one-quarter inch deep with edge II. The covering material or siding l9 may 66 56; inch shoulder. Wind seal strip I2 is con seen that-there-iifa'i'lrm sealing means at the bottom of siding which is the'point where the wind action is more serious. If desired the actual spaced construction shown at it in Fig.1 may be used so that a wedging action is obtained which will make certain that a complete meetingat line It is obtained before any meeting is obtainedat II. This construction will allow for any possible non-uniformity in materials or warping thereof due to possible weathering effects. It is thought to be more important that the seal at 20 and 21 beattained than that- 28 be open to'the weather and." and ll be closed. Special double groove and shoulder cutter is so constructed as to cut'groove II and 24 with one operation. As stated this construction is suggested merely for those cases where less care is used to produce a uniform siding construction. The present dis closure is intended as illustrative and not limiting. Many alterations of construction may be made without departing from the spirit of the invention.

I claim':

1. In a wall construction comprising sheathing, siding material arranged in overlapping courses, one above the other, the siding in one course bearing at their upper margin against the sheathing, the said siding material having channels on its rear face near and substantiallyparallel with the lower edge of the siding, thesaid channels partially closed by tongues projecting'toward each other, and horizontal sealing strips secured to the sheathing and a, portion of the said strip projecting into said channel, the said sealing strip of a configuration cooperating with the channels, and one tongue of each channel in forming a weather seal between adjacent courses of siding.

2. A siding-panel comprising a substantially rectangular board having on the rear face and adjacent the lower edge a channel, the said channel defining tongues projecting towards each other from a constricted entrance to the channel and outlining curved walls, the combination of a sealing strip having a substantially rectangular base and a top portion wider than the base and the said top .portion having a rounded shoulder coopcrating with one of said tongues and the curved wall of the channel in forming a weather seal.

3. A wall construction comprising, a base material; siding material arranged in overlapping courses, one above the other; the siding materialbearing at their upper margin against the base material, the said siding material having on its rear face, adjacent the lower edge a substantially horizontally extending channel, the said channel partially closed by tongues projecting toward each other anddefining curved walls; a horizontally mounted sealing strip on the upper face portion of a lower course of siding cooperating with said channel in forming a weather seal between adjacent courses of the siding; the said sealing strip having a base and a top portion of greater width than the base of the strip, but of less width than the entrance to the channel.
